Complete the following chemical equations
State reasons for the following
(i) Cu(I) ion is not stable in an aqueous solution.
(ii) Unlike Cr3+, Mn2+, Fe3+ and the subsequent other M2+ ions of the 3d series of elements, the 4d and the 5d series metals generally do not form stable cationic species
(i) This is because Cu(I) ion is unstable in aqueous solution and undergo disproportionation
(ii) This is because due to lanthanoid contraction the expected increase in size does not occur
